Description

Technical Field

[0001] The invention relates to the field of civil engineering construction, and in particular to a civil engineering construction material conveying system. Background Art

[0002] Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks and tiles, ceramics, glass, engineering plastics, composite materials, etc. In the design of steel structures in the fields of construction, steel column components are widely used. They are characterized by large size and heavy weight. Therefore, during the hoisting process, steel column components have strict requirements on hoisting equipment and operating processes. The hoisting of heavy components is dangerous, the hoisting process is risky, and the stability of the components is difficult to control, which has a great impact on construction safety.

[0003] The lifting process of large steel column components is very unstable. In the prior art, steel column components are generally placed horizontally at the unloading site, and the lifting point is set at the top of the steel column during lifting. Therefore, the lifting process involves a process of lifting the steel column component from a horizontal state to a vertical state; in addition, the steel column structure is currently mostly lifted in the form of sling bundling; the bundling form has the defects of low lifting efficiency, unreliable bundling, and easy damage to the paint surface of the component; and after the steel column is lifted into place, the bundling sling is not conducive to untying at high altitude, which is time-consuming and labor-intensive, and has great limitations in practical applications. Summary of the invention

[0004] In view of the defects in the prior art, the object of the present invention is to provide a civil engineering construction material conveying system that can stably transmit building prefabricated structures and improve the construction assembly efficiency.

The two lifting blocks of the lifting assembly are inserted into the lifting position of the prefabricated structure through the lifting port. During lifting, the lifting rope structure can be used to bypass the lifting pulleys on the two lifting blocks and then be mounted on the hook. Since the opening of the lifting port has a conveying roller, it is convenient to insert the lifting block into the lifting position of the prefabricated structure. After it is fully inserted into the lifting position, the elastic lifting mechanism is pressed down to ensure the stability of the lifting. After the lifting position is fixed, the prefabricated structure is lifted by the driving module, and the conveying platform is driven to move by the transmission assembly, so that the prefabricated structure is transferred to the loading and unloading position. During the loading and unloading process, the driving mechanism drives the push block to move to one side of the lifting port opening. During the movement, the lifting block can be removed from the prefabricated structure clamping position to achieve a quick unhooking operation. Since the sliding seat is connected to the lifting block through the connecting rope, it is convenient to perform subsequent lifting and transmission operations.

[0007] This device can quickly find the lifting center of gravity of the prefabricated structure during the lifting and transmission process. It is not easy to unhook during the lifting operation, and the hook body does not contact other areas of the lifting position, which can avoid damaging the paint surface of the component. After the lifting is completed, it can be quickly unhooked, thereby improving the convenience of lifting, transmission, loading and unloading and unhooking operations.

[0009] Furthermore, ratchet modules are provided at both ends of the lifting block, and the ratchet modules are connected to both ends of the conveying roller to enable the conveying roller to rotate in one direction.

[0010] Furthermore, the driving mechanism comprises a driving screw, one end of which is threadedly engaged with the pushing block, and the other end of which is transmission-connected to the power module, and a pushing bayonet is provided at the front end of the pushing block.

[0022] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0024] like Figure 1 and Figure 2 As shown, a specific embodiment of the present invention provides a civil construction material conveying system, including a lifting assembly and a transfer assembly; the lifting assembly includes a hook 100 and a sling 200, a lifting block 300 arranged opposite to each other is provided below the hook 100, a lifting pulley 400 is provided at the upper ends of the two lifting blocks 300, and the sling 200 is connected to the hook 100 after passing through the two lifting pulleys 400; a lifting opening 310 is provided at the opposite end of the lifting block 300, and a conveying roller 500 is provided on the opening top wall and bottom wall of the lifting opening 310 respectively, and an elastic lifting mechanism for elastically mounting the conveying roller 500 is provided on the opening top wall and bottom wall of the lifting opening 310, and a pushing block 600 is also provided in the lifting opening 310, and the pushing block 600 is connected to a driving mechanism arranged in the lifting block 300, and the driving mechanism can drive the pushing block 600 to move in the lifting opening 310; the transfer component includes a frame 700, and a conveying platform 800 is arranged on the upper end of the frame 700, and a transmission assembly 900 for driving the conveying platform 800 to move along the upper end of the frame 700 is arranged on the frame 700, and a driving module for driving the hook 100 to rise or fall is arranged on the conveying platform 800, and support parts 1000 arranged vertically are arranged at both ends of the frame 700; a sliding seat 1100 capable of sliding up and down along the support part 1000 is provided on the support part 1000, and a connecting rope 1200 connected to the lifting block 300 is provided on the sliding seat 1100.

[0025] like Figure 1 and Figure 2As shown, the conveying system provided in this embodiment can utilize the lifting assembly to lift and load and unload the prefabricated structure of civil construction when in use, and complete the transfer of the lifting object through the transfer assembly; the two lifting blocks 300 of the lifting assembly are inserted into the lifting position of the prefabricated structure through the lifting port 310; when lifting, the sling 200 structure can be utilized to bypass the lifting pulleys 400 on the two lifting blocks 300 and then be mounted on the hook 100. Since the opening of the lifting port 310 has a conveying roller 500, it is convenient to insert the lifting block 300 into the lifting position of the prefabricated structure. After it is fully inserted into the lifting position, the elastic lifting mechanism is pressed down to ensure the stability of the lifting. After the lifting position is fixed, the prefabricated structure is lifted by the driving module, and the conveying platform 800 is driven to move by the transmission assembly 900, so as to transfer the prefabricated structure to the loading and unloading position; during the loading and unloading process, the pushing block 600 is driven by the driving mechanism to move toward the opening side of the lifting port 310, and the lifting block 300 can be removed from the prefabricated structure clamping position during the movement to achieve a quick unhooking operation; since the sliding seat 1100 is connected to the lifting block 300 by the connecting rope 1200, subsequent lifting and transmission operations are convenient.

[0026] like Figure 1 and Figure 2 As shown, the device can quickly find the lifting center of gravity of the prefabricated structure during the lifting and transmission process, is not easy to unhook during the lifting operation, and the hook 100 body does not contact other areas of the lifting position, which can avoid damaging the paint surface of the component. After the lifting is completed, it can be quickly unhooked, thereby improving the convenience of lifting, transmission, loading and unloading and unhooking operations. In this embodiment, the transmission assembly 900 used to drive the conveying platform 800 to move can adopt a gear rack drive structure to achieve precise position transmission. The gear rack conveying structure belongs to the existing transmission technology and will not be repeated here.

[0027] As mentioned above, in this embodiment, the conveying roller 500 is installed by an elastic lifting mechanism to improve the lifting and fixing efficiency and facilitate unhooking and loading and unloading; in this embodiment, the elastic lifting mechanism specifically includes a lifting groove arranged on the top wall and bottom wall of the lifting port 310 opening, and a lifting block 1300 is arranged in the lifting groove, and the lower end of the lifting block 1300 is connected to a lifting spring 1400 located at the bottom of the lifting groove, and the two ends of the lifting block 1300 are rotationally matched with the two ends of the conveying roller 500. The two ends of the lifting block 1300 are also slidably matched with the side wall of the lifting groove. In this way, when the lifting position of the prefabricated structure is inserted into the lifting port 310 of the lifting block 300, the conveying roller 500 rolls and cooperates with the lifting position, thereby realizing rapid insertion. During the lifting process, the lifting position of the prefabricated structure generates downward pressure on the conveying roller 500, so that the lifting spring 1400 is compressed, thereby pressing the conveying roller 500 into the lifting groove; preventing the lifting block 300 from slipping off from the lifting position of the prefabricated structure. In addition, ratchet modules are provided at both ends of the lifting block 1300 in this embodiment, and the ratchet modules are connected to both ends of the conveying roller 500, so that the conveying roller 500 can rotate in one direction. In this way, since the ratchet module has the characteristics of one-way rotation and reverse locking, the conveying roller 500 forms a rolling fit with the lifting port 310 during the process of the prefabricated structure lifting position being inserted into the lifting port 310, thereby avoiding reverse rotation during the lifting process, and further preventing the lifting block 300 from slipping off the lifting position of the prefabricated structure. In addition, the top wall and bottom wall surface of the lifting port 310 of the frame 700 are provided with a supporting anti-skid layer, which can improve the stability of the lifting on the one hand, and avoid damage to the paint surface and other positions of the lifting position of the prefabricated structure on the other hand.

[0028] As mentioned above, the driving mechanism is used to drive the push block 600 to rotate in the lifting port 310, so as to realize the quick unhooking operation. The driving mechanism in this embodiment includes a driving screw 1500, one end of which is threadedly engaged with the push block 600, and the other end is connected to the power module 1600, and a pushing bayonet is provided at the front end of the push block 600. In this way, when the driving screw 1500 rotates under the drive of the power module 1600, the push block 600 can be moved in the lifting port 310, and the lifting block 300 can be removed by clamping the lifting position end of the prefabricated structure with the pushing bayonet.

[0029] like Figure 1 and Figure 2As shown, in order to prevent the lower end of the prefabricated structure from sliding during the actual hoisting and transmission process, the present embodiment provides support arms 1700 that can move up and down along the support parts 1000 on the support parts 1000 at both ends of the frame 700, the support arms 1700 can be extended and retracted horizontally, the support arms 1700 are provided with a hydraulic module that drives the support arms 1700 to extend and retract horizontally, and the front end of the support arms 1700 is provided with a positioning abutment 1800 that can roll with the outer surface of the lifting part. In this way, during the lifting process, the support arms 1700 are deployed to make the positioning abutment 1800 abut against the outer periphery of the prefabricated structure, which plays a balancing and positioning role, and prevents the prefabricated structure from shaking. In addition, since the positioning abutment 1800 can roll with the outer surface of the lifting part, damage to the surface of the structure can be avoided. In addition, in this embodiment, a rotating platform 1900 is provided at one end of the support arm 1700 away from the positioning and abutting portion 1800, and the rotating platform 1900 is rotatably mounted on the support portion 1000. The rotating platform 1900 can drive the support arm 1700 to rotate, avoiding interference with the lifting and transmission operations when positioning is not required.

[0030] like Figure 1 and Figure 2 As shown, in actual application, when the prefabricated structure is hoisted to a vertical position, installation and fixing operations need to be performed. In order to facilitate technicians to enter the corresponding workstations to carry out construction, an operating platform 2000 is provided at the upper end of the support parts 1000 at both ends of the frame 700 in this embodiment. A guardrail is provided at the edge of the operating platform 2000, and an operating ladder 2100 extending toward the lower end of the support part 1000 is provided on the outer side of the supporting part 1000 corresponding to the operating platform 2000. In this way, when construction is required, construction personnel can enter the operating platform 2000 from the operating ladder 2100 to carry out corresponding construction operations at the upper end of the prefabricated structure, and the safety of construction operations can be improved by providing a guardrail.

[0031] like Figure 1 and Figure 2 As shown, the device is mainly supported by the support part 1000 during the transmission construction process. In this embodiment, a fixed platform 2200 is provided at the lower end of the support part 1000 at both ends of the frame 700, and a hydraulic support assembly 2300 is provided on the fixed platform 2200. In this way, the hydraulic support assembly 2300 can support the entire device and improve stability; in addition, the support part 1000 provided in this embodiment includes a plurality of support frame monomers, the support frame monomers are detachably connected from top to bottom, and the support frame monomers are provided with a matching guide rail 2400 that is slidably matched with the sliding seat 1100. The support part 1000 adopts a support frame monomer that is detachably connected from top to bottom. In actual application, the number of support frame monomers can be selected according to needs, so as to control the height of the entire device. The support frame monomers are fixed using the existing technology, which will not be repeated here.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
